Abstract

The present invention concerns biomarkers and use thereof for determining whether a subject is or is not susceptible to developing a prophylactic or therapeutic immune response after such treatment.

Description

Be used to select patient's biomarker and correlation technique
The present invention relates to field of immunology, particularly to the patient being carried out immunization therapy by for example infecting caused disease or cancer.More specifically, the present invention relates to be used for after this kind immunization therapy, predict whether the patient is easy to produce preventative or therapeutic is replied, preferably the method for immune response.The present invention relates to through immunogenic composition, particularly therapeutic vaccine improves the method and composition of patient's to be treated survival rate.
The routine immunization technology knows that for the people it relates to introduces antigen (like peptide, protein) in animal system for a long time, but this antigen induce immune response, thus said animal is provided to the for example protection of infection.These technology also comprise exploitation live vaccine and inactivated vaccine.Live vaccine generally is the avirulence form through attenuation of infector, can cause the immune response to the pathogenic form of this infector.
Many research groups also after deliberation vaccine as purposes to the potential therapeutic modality of multiple cancer types.The particular type of this vaccine strategy is commonly referred to as immunization therapy.
In recent years, the research and development of recombinant vaccine, particularly live recombined vaccines have obtained progress, wherein vector encoded and expression purpose exogenous antigen.Wherein, shown very promisingly based on the carrier of recombinant virus, and in the exploitation of novel vaccine, played a significant role.To many virus researches its express ability from the protein of foreign pathogens or tumor tissues, and induce ability in vivo to the specific immune response of these antigens.These vaccines based on gene generally can stimulate body fluid and cellullar immunologic response efficiently, and viral vectors possibly all be an efficient strategy for delivery of antigens encoding gene and promotion and enhancement antigen are presented.For as vaccine carrier, desirable viral vectors should be safe, and can efficiently present required pathogen specific antigen to immune system.In addition, carrier system must satisfy the standard that it can large-scale production that makes.Therefore, some viral vaccine carriers have appearred at present, they according to the application that is proposed all have relative advantage and limitation (summary of recombinant viral vaccine is consulted like Harrop and Carroll, 2006, Front Biosci., 11,804-817; Yokoyama etc., 1997, J Vet Med Sci., 59,311-322).
Observe the DNA carrier in vivo after the direct transfection zooblast in phase earlier 1990s, carried out a large amount of research and developed through the DNA that directly in animal, introduces coding for antigens based on using the DNA plasmid to come the immunity inoculation technology of induce immune response.These technology that are commonly referred to as the dna immunization inoculation have been used for causing protective immune response at a large amount of disease models at present.The summary of dna vaccination is consulted Reyes-Sandoval and Ertl, 2001 (Current Molecular Medicine, 1,217-243).
Yet, be to identify in the individuality of inoculation, to induce enough strong immune response to avoid infecting the means with disease in the general issue in vaccine field, thereby prolongation suffers from the for example patient's of cancer the survival of mortality disease with protection and/or treatment.
Therefore, carry out the oxadiazole derivatives as comt inhibitors that extensive work finds that some critical aspects through stimulating immune system plays a role in recent years, be used to improve vaccine-induced immune response.As if most these compounds (being called immune response modifier (IRM) or adjuvant) all pass through the fundamental immunity system mechanism, induce multiple important cytokine (for example interferon, interleukin, TNF etc. via Toll appearance acceptor (TLR).Consult like Schiller etc., 2006, Exp Dermatol., 15, biosynthesizing 331-341) plays a role.These compounds have shown stimulates the rapid cell factor that some T cell, dendritic cells or monocyte/macrophage are derived that discharges; Can also stimulate lymphocyte function, for example the antibody that in the antiviral and antitumor activity of IRM compound, plays a significant role of B emiocytosis.
Alternatively, the immunity inoculation strategy has been proposed, wherein most schemes that are based on initiation-booster immunization inoculation.According to the immunization scheme of these " initiation-reinforcements ", at first immune system is induced through the patient is used triggering composition, strengthen (consulting) through second composition of using reinforcement then like EP1411974 or US20030191076.
In addition, shown that in the health care background a kind of treatment maybe be only effective in the patient of particular group.Therefore hope to make them can customize the tool and method of best personalized patient therapy for the doctor provides; Promptly indicate suitable therapy so that higher treatment success ratio to be provided at reasonable time to suitable patient, monitoring improves pharmaceutical efficacy and security to the reaction of treatment; Elimination is to patient's unnecessary treatment (to the inappropriate therapy of patient); Reduce patient's unnecessary toxicity and spinoff, reduce the expense of the unnecessary or dangerous invalid medicine of patient and insurance company, and improve patient's quality of life; Finally make cancer become controlled disease, and according to circumstances follow-up is measured.
In this, document has proposed multiple tool and method, for example:
-pharmacogenetics, it comprises according to the research of hereditary difference to the individual reaction of medicine.These reactions relate to medicine and how in any given individuality, to bring into play function, and how it is by metabolism, its toxicity and dosage requirement.Along with the development of the Human Genome Project, pharmacogenetics has been expanded as pharmacogenomics.Pharmacogenomics has surmounted pharmacogenetics, possibly in drug discovery and exploitation, target discovery and affirmation and clinical testing, play a role.
-also can use metabolism group (Metabolomics) in the prospective medicine field.Genic pharmacogenetics is different with being confined to, and the drug metabolism group can be not only based on inherent cause but also based on non-genetic factor, the other drug in patient's body for example, the individual reaction to medicine of health status that the patient is present or the like prediction.
-biomarker has more and more important effect in therapeutic clinical development.Biomarker can be normal biological process, lysis or the indicator of pharmacological reaction that treatment is intervened.Its reach is from dividing into groups to patient colony to help to identify respondent and non-responder, to measure the effectiveness of treatment.Biomarker can be used as valuable instrument be used to better to make a strategic decision with the expense that reduces drug development with make treatment be applied to optimal patient colony quickly.
The invention provides and use biological markers (biomarker (biomarker)) prediction to relate to the patient is used material and the method that the treatment of immunogenic composition (being the immunotherapy treatment) is renderd a service, said biomarker confirmed be and the relevant believable basically signal of expection clinical effectiveness.Before with the treatment of said immunogenic composition, biomarker is present in the biological sample that obtains from the patient.The ability of the clinical effectiveness of predicted treatment makes clinician and patient can identify invalid treatment before treatment beginning, to the decision-making of knowing the inside story of associated treatment process, comprises whether abandoning or allow to implement alternative therapy.
